When you start orthodontic treatment, you should only do so once your orthodontist has presented you with a plan. The plan is drawn up from an analysis of all the information about the patient – dental models, X-rays, photographs and, if needed, additional consultations with other specialists. The plan is very important for achieving the result you want from orthodontic treatment. It gives the patient clarity about what to expect, what can change in their smile and what difficulties are expected in aligning the teeth. The plan also protects the specialist, giving them confidence that the patient understands the treatment ahead and has correct, realistic expectations. The other side of orthodontic treatment is the technical execution of the plan, which depends on the orthodontist's skill, knowledge and experience.
This answer is for general information. Your own case needs an examination by an orthodontist.
